Centrifugal Compressor Demonstration Apparatus MODEL FM 98

Sci-tech Centrifugal Compressor Demonstration Apparatus Model FM 098 features a two-stage radial compressor with variable speed via a frequency converter, an intake pipe and a delivery pipe. The intake and delivery pipes are transparent. A protective plate placed in front of the inlet of the intake pipe prevents larger objects from being drawn in or the clogging of the intake opening. The air flow is adjusted by a throttle valve at the end of the delivery pipe.

Size: 70cm x 60cm x 90cm (LxWxH)
Weight: 35 kg

Item Description

Features

  • Illustrative model of a radial compressor
  • Transparent delivery pipe and intake pipe
  • Software for data acquisition, visualization and operation
  • Part of the fluid energy machines

Radial compressors are used to compress gases. The medium is drawn in axially to the drive shaft by the rotation of the rotor and flows through the rotor rotating at high speed. By means of centrifugal force, the medium is accelerated towards the outer edge and is compressed in this manner.

The experimental unit provides the basic experiments to get to know the operating behavior and the important characteristic variables of radial compressors.

The intake and delivery pipes are transparent. A protective plate placed in front of the inlet of the intake pipe prevents larger objects from being drawn in or the clogging of the intake opening. The air flow is adjusted by a throttle valve at the end of the delivery pipe.
The experimental unit is fitted with sensors for pressure, temperature and speed. The flow rate is determined via differential pressure measurement on the intake nozzle.
The microprocessor-based measuring technique is well protected in the housing. All the advantages of software-supported experiments and evaluation are offered by ‘Sci-Cal’ software and the microprocessor. The connection to a PC is made by USB.

The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
